T0 00% whom it may concern:

Be it known that I, HOMER S. GALLUP, a citizen of the United States, residing at Waurika, in the county of Comanche and Oklahoma Territory, have invented a new and useful Acetylene-Gas Generator, of which the following is a specification.

This invention relates to acetylene-gas generators, and has for its principal object to provide a device of simple construction whereby carbid may be automatically fed to the generating-tank each time the supply of gas in the gasometer is reduced.

A further object of the invention is to constructa novel form of generator in which the gasometer-bell isarranged to receive and hold the gas generated and to permit the outflow of gas to the service-pipe while fresh quantities of gas are bein made.

A still further object of the invention is to provide an ap aratus of this type in which the carbid-ho der and the generating-tank proper are in the form of separate vessels which may be readily removed when neces sary.

A still further object of the invention is to provide a novel form of carbid-feed valve in which the valve is opened by the descent of the bell and is returned to closed position by means of springs.

With these and other objects in view, as will more fully hereinafter appear, the invention consists in certain novel features of construction and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that varlous changes in the form, proportions, size, and minor details of the structuremay be made without departing from the spirit or sacrificing any of the advantages of the invention.

In the accompanyin drawings, Figure 1 is a sectional elevation 0 an acetylene-gas generator constructed in accordance with the invention. Fig. 2 is a sectional plan view of the same on the line 2 2 of Fig. 1. Fig. 3 is a detail perspective view of the valve and its carryingbar.

Similar numerals of reference are employed to indicate corresponding parts throughout the several figures of the drawings.

In carrying out the invention a asometer 10 of annular form in sectional p an is em ployed. The water-containing tank is pro- The gasometer-bell 17 is also annular in form in sectional plan and has a verticallyextending neck 18, forming a continuation of the inner wall of the bell, the neck being arranged to extend some distance above the t inner wall 13 of the tank. At the top of the neck is a small annular casing 20, which may be filled with liquid to form a seal for the vertical flange of a cover 21, that is held in place by a number of spring-catches 22, which may be readily drawn outward in order to release the cover whenever it becomes necessary to gain access to the interior of the generator. The springs are so arranged that they look automatically over the edge of the cover when the latter has been forced down into position.

Within the lower portion of the annular wall 13 is arranged a generating-tank 24, having an upper flaring edge, and the sides and bottom of the tank being spaced from the bell in order to form a free passage for the gas, so that the gas may pass through a pipe 25 at a point below the generating-tank and upward through a pi e 26 into the gasometer at a point above t e water level thereof. These two pipes communicate with a servicepipe 27, through which the gas is led off to the point of consumption. In the pipe 25 is a one-way check-valve 28, opening outward to permit the free passage of gas to'the gas01neter and arranged to close to prevent the backflow of gas into the space around the generating-tank.

The carbid-holder 30 is in the form of a cylindrical casing of less diameter than the diameter of the inner wall 13 of the tank and is supported by two or more standards 31, which rest on the to of the generating-tank 24, and these stanc ards have vertical slots for the passage of ,the bar 15, so that said bar may project through the standards and through the slots 14 into the path of move ment of a flange or lugs 33, that project inward from the neck 18 of the bell.

' The carbid-holder is provided with a bottom discharge-neck 34, which may be closed by a conical valve 35, carried by the crossbar 15, and said valve is normally held in 1 and allowing a quantity of carbid to fall from the holder into the generating-tank 24. As soon as the gas is formed the bell will rise and the springs 36 will draw the valve to its closed position. During this operation the gas is held from return movement to the space around the generating-tank by the closing ofthe check-valve 28.

The apparatus is entirely automatic in its nature, and gas will be generated so long as any of the carbid remains. When necessary, the cover 21 may be removed and the carbidholder replenished, or the carbid-holder may be lifted out and then the generating-tank removed should it become necessary to clean out the carbid-slush and replenish the water.

I claim 1. In acetylene-gas apparatus, a gasometer including an annular tank and an annular bell, the inner walls of both the bell and tank being vertically extended, a generatingtank arranged in the lower central portion of the tank, a carbid-holder mounted above the generating-tank and provided with a discharge-opening, a valve for closin the opening, springs tending to maintain the valve in closed position, a bar carrying the valve, means on the inner wall of the bell for engaging and depressing the bar, and a removable cap for the inner portion of said bell.

2. In acetylenegas apparatus, a gasometer including an annular tank and an annular bell, a removable cap for the central por tion of the bell, a connecting-pipe between the central and annular spaces of the gasometer, a check-valve arranged in the pipe and serving to prevent backfiow of gas from the annular space, a removable generating tank in the lower central space of the main tank, a carbid-holder, a spring-closed valve therefor, a bar carrying the valve, and means on the bell for engaging said bar and moving the valve to open position.

In testimony that I claim the foregoing as my own I have hereto afiixed my signature in the presence of two witnesses.

HOMER S. GALLUP.
